An apparatus for dry cooling red-hot coke having an antechamber with a small discharge leading to a vertically elongated cooling chamber which is of larger dimension than the discharge and with both the cooling chamber and the antechamber having fluid cooling tubes in one or more walls and the ceiling thereof and also having a cooling tube bank in the shape of truncated pyramid comprising trapezoidal walls diverging downwardly from the discharge of the antechamber into the cooling chamber.

Apparatus for dry cooling red-hot coke

A waste heat boiler system includes a vertically elongated waste heat boiler having an upper portion with a waste gas inlet and a lower portion with an exhaust line connection which in addition to its vapor generating tubes includes evaporator tube nests and a water preheater. The waste gases are received from a dry coke cooling vessel and they are delivered through a separator by a blower to the lower end of the coke cooling vessel for flow upwardly through the hot coke. The superheater is mounted over the waste heat boiler and has a connection through a controllable valve to the top of the waste heat boiler. The superheater includes its own burner and air and external gas supply are supplied to the combustion chamber for the superheater along with bypass portion of the circulated waste gases. The steam generated by the boiler is delivered from a steam cylinder or drum in the superheated tubes of the superheater. Some of the gases from the superheater are selectively delivered to the waste heat boiler and some are discharged through atmosphere.

Method for cooling coke and generating superheated high pressure steam

A method of dry cooling red-hot coke in a vessel having an antechamber with a small discharge leading to a vertically elongated cooling chamber which is of larger dimension than the discharge and with both the cooling chamber and the antechamber having fluid cooling tubes in one or more walls and the ceiling thereof and also having cooling tube bank diverging downwardly from the discharge of the antechamber into the cooling chamber, comprises directing the red-hot coke to be cooled downwardly through the antechamber and into the cooling chamber so as to maintain a charge of coke in the cooling chamber to the conical charge cone of the cooling tubes adjacent the top of the cooling chamber which extends downwardly below the discharge, thereafter circulating a coolant through the cooling tubes to effect transfer of sensible heat from the coke to the fluid and directing a cooling gas from the bottom of the cooling upwardly through the coke and above the entire area of the coke charging cone and then into an exhaust duct to one or more waste heat boilers.

Method for dry cooling red-hot coke

A dry coke cooling apparatus comprises an antechamber with a bottom hole for charging coke into a cooling chamber which accommodates vertical outer cooling walls and inner cooling walls which extend within the coke charge. The lower part accommodates coke discharge equipment and conduits for supplying circulated cooling gas which passes upwardly through the charge, to be exhausted at the top. The inner cooling walls are supported on hollow beams which are cooled by the circulated cooling gas directly or indirectly.

In a method of stripping ammonia from water using steam in countercurrent flow, wherein steam is supplied over a sump of a stripper and directed along with the stripped gas component from a head of the stripper, the method comprising keeping the counterpressure constant while the temperature of supplied ammoniacal water is elected and the partial pressure of the component to be stripped is correspondingly lowered by adding compressed saturated vapors which have not been cooled and correspondingly reducing the steam volume.

The invention makes possible a coking operation largely or completely eliminating waste water by converting the gas condensates obtained from the coking plant by a reverse osmosis process into a permeate which can be recycled to the coking operation, and a concentrated lye.

Treatment of gas condensates

A coke-oven door for use in combination with a coke-oven chamber having an upright doorjamb has a door panel whose periphery is complementary to the doorjamb and which is provided with a seal extending around that periphery between the same and the doorjamb. A plug with a heat-insulating outer wall is carried on this panel within the seal and projects through the doorjamb into the chamber. This plug is formed with a vertically extending and upwardly open passage bounded by a metallic inner wall having gaps by which gases produced during coking adjacent the plug enter the passage on their way to a flue, exchanging heat through the metallic wall with the charge in the oven and thereby aiding the coking operation.

Method of operating a coke oven

A coking chamber of a coke-oven battery, with heated longitudinal walls interconnected by a doorjamb at each end, is closed by a pair of doors sealingly fitting into these doorjambs. Each door has a vertical channel separated from the exterior by an outer wall with a heat-insulating layer and from the interior of the chamber by an upright metal plate facilitating thermal conduction therebetween. The channel is accessible at various levels or over its entire length to gases evolving from a charge inside the chamber which, in rising toward the roof of the chamber, retransmit some of their heat through the metal plate to the charge for enabling substantially uniform heating thereof from four sides.

A process and apparatus for the dry cooling of coke involves the provision of a vessel having therein first and second zones in full communication with each other. Hot coke from a coking operation is introduced into the first zone and is passed through the first and second zones. Raw coke oven gas from the coking operation is introduced into the first zone, thereby reducing the temperature of the coke, while cleaning the raw coke oven gas to form cleaned coke oven gas. The cleaned coke oven gas is removed from the first zone, cooled, and then directly or indirectly utilized as a heat carrier gas introduced into the second zone to therein further reduce the temperature of the coke. The thereby further cooled coke is removed from the second zone.
